Solution Overview

Problem

Existing stair scaffolding systems face challenges in simplifying and accelerating assembly and dismantling, especially at greater heights, while maintaining static stability and requiring efficient space usage and transport.

Innovation Solution

A modular stair scaffolding system with vertically oriented posts and detachable horizontal bars, featuring perforated disk connection elements for adjustable and symmetrical configuration, allowing for easy assembly and disassembly, and enabling space-saving transport and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional stair scaffold towers are assembled successively from bottom up, then the structure can be built with simple components, but assembly and dismantling become time-consuming and complex at greater heights

Engineering Contradiction:
Improveassembly speedVSAvoidassembly complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The stair scaffold tower is divided into modular units, each comprising a vertical post with integrated horizontal beams and stair units. This segmentation allows pre-assembled modules to be quickly stacked and connected, significantly reducing assembly time and complexity compared to traditional component-by-component assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional elements (vertical posts, horizontal beams, and stair units) are merged into integrated modular units. The horizontal beams are detachably connected to vertical posts within each module, and stair units are attached to these beams, creating self-contained assemblies that simplify the overall construction process.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If stair scaffold towers use fixed rigid connections, then static stability is ensured, but adaptability and ease of disassembly are reduced

Engineering Contradiction:
Improvestatic stabilityVSAvoidassembly flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connection system uses detachable mechanical joints between horizontal beams and vertical posts, allowing the structure to transition between fixed (during assembly) and movable (during disassembly) states. This dynamic connectivity maintains stability when assembled while enabling easy reconfiguration and disassembly.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The detachable connection elements serve multiple functions: providing structural stability when connected, enabling easy disconnection for disassembly, and allowing reconfiguration for different tower heights and configurations. The same connection mechanism handles both stabilization and adaptability requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If complete stair scaffold towers are transported to construction sites, then assembly time is reduced, but transport and storage space requirements increase significantly

Engineering Contradiction:
Improveon-site assembly speedVSAvoidtransport volume
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The stair scaffold tower is segmented into modular units that can be compactly transported to construction sites. Each module contains integrated components (posts, beams, stair units) that fold or nest together, reducing transport volume while maintaining the ability to quickly assemble complete towers on-site through simple stacking and connection.

Inventive Principle:
Principle #1Segmentation
